I, TONYA (15) HHHH H.
ACCORDING to a title card at the beginning of Craig Gillespie's blackly humorous biopic, I, Tonya is based on "irony free, wildly contradictory, totally true interviews" with US figure skating champion Tonya Harding and her ex-husband Jeff Gillooly.
The film illuminates a grubby episode in sporting history - the 1994 attack on skater Nancy Kerrigan - with considerable aplomb.
The deeply flawed protagonists talk directly to camera, offering contradictory and overlapping testimonies that make sense of the chain of events that led to Harding's ban from competitive skating.
Margot Robbie inhabits the title role with fearlessness and ferocity while Sebastian Stan oozes slippery charm as Gillooly, who exerts his marital "right" to lay his hands on her in anger.
Whether we believe Tonya or not, she recounts a cracking yarn of triumph against adversity.
